FIELD: heat-and-power engineering.
SUBSTANCE: invention relates to the field of heat power engineering and can be used in heat supply systems. Control system of the hydraulic mode of operation of the boiler system of heat supply contains the first pressure sensor, installed on the return line of the heating system and electrically connected to the first control unit connected to the engine of the make-up pump, the second pressure sensor is installed on the supply line and electrically connected to the second control unit, that is connected to the motor of at least one network pump. Each control unit is connected to a corresponding pressure setpoint.
EFFECT: system provides the possibility to control the change and stable maintenance of the velocity of the coolant movement outside the boiler room in the pipelines of the heating network and on the systems of the heating devices of the heat consumption objects.
